Answer:

12.92cm²

Step-by-step explanation:

[tex] area = \frac{1}{2} \times base \times height[/tex]

area= 1/2×7.6×3.4

Area = 1/2 × 25.84

Area = 12.92 cm²

Answer:

3125*k^9 + y^3 is an integer my closure property.

 but 5^(1/3) is not an integer, which forces z to be irrational.

Note that there is no way an integer value can rationalize 5^(1/3)

Step-by-step explanation:

x^3 = 25z^3 - 5y^3

x^3 = 5 ( 5z^3 - y^3)

x  =  (5 ( 5z^3 - y^3) )^(1/3) must be an integer

  = 5^(1/3) * (5z^3 - y^3)^(1/3)

Then  (5z^3 - y^3)^(1/3) = 25*k^3 for some integer k

 5z^3 - y^3 = 15625*k^9

 5z^3 = 15625*k^9 + y^3

  z^3 = 3125*k^9 + (1/5)*y^3

z =  ( 3125*k^9 + (1/5)*y^3 )^ ( 1/3)

Answer:

Slope is  - 9, y-intercept is 7.

Step-by-step explanation:

f(x) = 3x - 5

g(x) = f(x+4) = 3(x+4) - 5= 3x + 12 - 5 = 3x + 7

h(x) = 3( - 3x) + 7 = - 9x + 7

h(x) = - 9x + 7

Slope of h(x) is  - 9, y-intercept is 7.

Answer:

4

Step-by-step explanation:

In the equation y=mx+b

b is the the value of y in the y-intercept

so change 2x+3y=12 into y=mx+b (Subtract 2x from both sides)

so 3y+2x-2x=12-2x

so 3y=-2x+12 (divide by 3)

y=-2/3x+4 so

(0,4) or

4 is the y-intercept.

Answer:

No solution

Step-by-step explanation:

4+ 2(5x-8)=ax+b

1. Plug in values: 4 + 2(5x-8) = (10)x + (-4)

2. Combine Like Terms: 4 + 10x -16 = 10x -4

3. Add 10x to both sides: 4 -16 = -4

4. Combine Like Terms: -12 = -4

-12 does not equal -4, so there is No solution

answer:

Step-by-step explanation:

Just divide 1500 by 100

To solve this we need to make a proportion

[tex] \dfrac{1}{100} = \dfrac{x}{1500} \\ x = \dfrac{1 \times 1500}{100} \\ x = 15 \%[/tex]

∠2 and ∠7 ↔ Alternate Exterior Angles

∠4 and ∠5 ↔ Alternate Interior Angles

∠3 and ∠6 ↔ Alternate Interior Angles

Answer:

x=4

Step-by-step explanation:

y = 2x - 8

Let y =0

0 = 2x-8

Add 8 to each side

8 = 2x-8+8

8 = 2x

Divide each side by 2

8/2 = 2x/2

Step-by-step explanation:

Answer:

Step-by-step explanation:

5.67x - 8.16 + 3.6x + 9.2

Write the like terms together

= 5.67x + 3.6x - 8.16 + 9.2  

{8.16 & 9.2 have different sign, so subtract and the result will have the bigger numbers sign}

= 9.27x + 1.04

Answer:

  5 + y = -2

Step-by-step explanation:

To get 5 more than a number, you need to add 5 to the number. Then "5 more than y" is "5+y" or "y+5".

In math, "is" means "is equal to."

5 more than a number y is negative 2 means ...

  5+y = -2

Answer:

[tex]5 + y = ( - 2)[/tex]

Step-by-step explanation:

Five more than a number means,

[tex]5 + y \: \: \: \: or \: \: \: \: y + 5[/tex]

is means equal to.

[tex] = [/tex]

is negative 2

[tex] = - 2[/tex]

Now let's create the equation,

5 more than a number y is negative 2

[tex]5 + y = (- 2)[/tex]

Answer:

[tex](x + 12) + 3x = 180[/tex]

Step-by-step explanation:

4x=168

x=42 left

x+12=54

3x=126 right

Answer:

(x+12)+3x=180

Step-by-step explanation:

Hope it helps you in your learning process

(x+12)+3x=180. (straight line angles)

4x + 12 = 180

4x = 180 - 12

4x = 168

x = 168/4

x = 42°

Answer:

a) 35km

b) 070 degrees

C) Check the photo to see what I did

Step-by-step explanation:

To get full marks look at what I did for question (c)

You have to use a protractor on letter s and make sure the 0 on the protractor is facing the letter (N). Now check where 90 degrees is and draw a line straight by using the ruler then use the compass as u can see in the photo, where (x) point is on the end of the compass is your answer {make sure the compass is 2cm which means its 20km. Also make sure to align the compass on the line you drawn}

Thank you

The real distance between the ship and the base is 35 km and the measure of the bearing of B from S is 70 degrees.

Scale factor is the factor which is used to enlarge or smaller the original figure.

Scale factor is the ratio of representation measurement of the figure to the original figures.

The diagram shows the position of the ship(S) and the marine base(B). The image of the ship is attached below.

When the distance of the attached image from ship and the base is measured by rules. It comes out 3.5 cm.

The scale of the diagram is 1 cm, represents 10 km. Thus, the real distance is,

[tex]BS=\dfrac{10}{1}\times3.5\\BS=35\rm\; km[/tex]

With the help of compass, the bearing angle of B from S is measured as,

[tex]\angle BSN=70^o[/tex]

Thus, the real distance between the ship and the base is 35 km and the measure of the bearing of B from S is 70 degrees.

The value of the expression [tex]m^{2} + 3m[/tex] when m =4 is 21.

An expression is a combination of numbers, variables, functions such as addition, subtraction, multiplication or division etc.

The process of swapping an algebraic letter for its value is called substitution.

According to the given question we have

An expression

Answer:

Proved (See Explanation)

Step-by-step explanation:

Show that 3ⁿ⁺⁴ - 3ⁿ is divisible by 16.

This is done as follows

[tex]\frac{3^{n+4} - 3^n}{16}[/tex]

From laws of indices;

aᵐ⁺ⁿ = aᵐ * aⁿ.

So, 3ⁿ⁺⁴ can be written as 3ⁿ * 3⁴.

[tex]\frac{3^{n+4} - 3^n}{16}[/tex] becomes

[tex]\frac{3^n * 3^4 - 3^n}{16}[/tex]

Factorize

[tex]\frac{3^n(3^4 - 1)}{16}[/tex]

[tex]\frac{3^n(81 - 1)}{16}[/tex]

[tex]\frac{3^n(80)}{16}[/tex]

3ⁿ * 5

5(3ⁿ)

The expression can not be further simplified.

However, we can conclude that when 3ⁿ⁺⁴ - 3ⁿ is divisible by 16, because 5(3ⁿ) is a natural whole number as long as n is a natural whole number.
